I've had some problems with reverse and have some questions and
thoughts:
1. When I add a view and a corresponding entry in urls,py, sometimes I
get a reverse error until I stop the dev server and restart it, even
though nothing is wrong with either file. Is there an order in which
those changes should be made that guarantees this won't happen?
2. The doc says templates are intended to be editable by designers/non-
programmers. But any {% url view arg %} tag that is not 100% correct
(both view and arg) will bring down that page, not just cause a broken
link.
The error message usually points to the first {% url %} tag, which may
be in a base template not in the template that actually contains the
error.
3. The details given in the error messages for reverse are very
misleading. The error is almost always elsewhere and the arguments
are usually irrelevant. It is not good policy to imply a specific
error location when the error system has no idea where the problem
is.
4. One improvement would be something (in the dev server?) that does
some basic comparison of urls.py and views. Django has access to
all the URL patterns and all the views modules, so couldn't it compare
the views in one to the views in the other and warn you if there is a
mismatch? This would not require reversing the Regexes, just making
sure the view functions referenced in urls.py are all present in
views. That would localize one source of reverse errors.
5. If the checking specified in #4 finds no errors, wouldn't that
mean the error must be in the template? At that point, would it be
possible to localize {% url %} tag errors to show the context of the
error? If the template loader combines base templates with sub-
templates, then the line number is of limited use so the context would
be more useful.
I understand this is a difficult problem, but I've found this
frustrating and believe
it could be improved.
I'm running 1.0.2 and if this have been improved already, then great.
